No more time-consuming rotor & swing pipe assembly – We have done all the hard work for you! A set of three of our best-selling Hunter PGP Ultra 4" Rotor Pop-Up Sprinklers with Nozzle Pack, Swing Joints & Compression Fittings, each Rotor arrives pre-assembled and is ready to be installed within your existing pipe network.
Lawn Watering Irrigation Solutions
Enjoy the time-saving benefits of an irrigation system! This pre-assembled solution has all the hard work done for you. Arrives complete with 12 standard nozzles including 4 grey ‘low angle’ nozzles ideal for watering lower trajectories and providing effective irrigation for even the most complex landscapes. Hunter Wrench (sold separately).
3 x Hunter PGP Ultra 4" Rotor Pop-Up Sprinklers with Nozzle Pack
The Hunter PGP Ultra Rotor is complete with a no-flow-by riser seal made from high-quality material for exceptional protection against leaks. Proven and tested with over three decades of research for ultimate reliability and performance.
Enables diverse watering with a radius between 4.9 to 14 metres ideal for an array of efficient irrigation options.
Easily adjust or switch off the sprinkler at the head using either a Hunter Wrench (not included) or a flat-blade screwdriver.
3 x Hunter Swing Joint 3/4" x 3/4" - 12" Long
For ultimate flexibility when placing your rotor at its sub-surface location, this swing joint enables easy routing of sprinkler heads at any angle from the lateral pipe.
3 x HydroSure Tee Compression Coupling Female 25mm x 3/4" x 25mm
Enabling an easy one-step installation process, this compression tee fits standard-sized 25mm MDPE & HDPE pipe. Promising a watertight connection and a smooth internal bore for maximum water flow, this fitting helps to enhance emitter performance by limiting pipe friction.
PTFE Thread Seal Tape
No more time-consuming installation! Each male thread has been wrapped with PTFE tape for secure irrigation joints and ultimate protection against leaking connections.
Underground systems require frequent flushing to prevent dirt from clogging the nozzle or damaging the seal. Flush the system and clean the rotors if necessary to remove any sitting sediment.
Any damage to the riser caused by a mower or footfall will cause mechanical malfunction and disfigured spray patterns. Check each nozzle and turret top of your sprinklers to ensure they are intact.
The area around a sprinkler site may become boggy/waterlogged indicating a loose connection between the swing joint/fitting or a break in the pipe network. To repair a leak, use a Compression Joiner or Barbed Joiner depending on the pipe used or install PTFE Tape around any male threaded connection to ensure a watertight seal.
Water leaking from sprinkler sites even when the system is switched off indicates a problem called low head drainage. A pop-up sprinkler with a Check Valve will prevent water pooling from sprinklers installed at the lowest elevation.
My Sprinklers are not Working the
Same as when Purchased!
Over time a sprinkler may experience a build-up of sediment and debris that blocks the nozzle outputs or damages the riser retraction mechanisms inside the sprinkler. Flush the system and clean out the rotor sprinkler as explained in our Sprinkler Maintenance Guide.
Prevent debris build-up by installing an Irrigation Filter at the start of the system. • Alternatively, leaking connections or a pipe supplying the sprinkler may have split. The water lost from connections that are not watertight will cause pressure loss and reduce performance.
Why are my Underground Pipe
Connections Leaking?
An area that is boggy or waterlogged indicates a leaking connection or a pipe that may have split. Most connection points can be tightened by hand or by adding two wraps of PTFE Tape around male threads or replacing connectors that over time, have snapped.
When fixing your pipe network, depending on the pipe you are using to supply your system will indicate the type of connector you need to repair the damage.
My Sprinkler Does Not Cover the
Range/Radius Outlined in the Specifications
A variation in flow rate or pressure drop from the water source will also reduce the performance of sprinklers – Check the flow rate from your tap remains high enough during the time of day your system is set to run using our Calculating Flow Rate from the Water Source Guide.
On windy days, the spray pattern from your sprinklers may alter even when using nozzles with built-in wind resistance. Alternatively, running a system at a bar pressure that is too high, will create misting – Consider installing a Pressure Reducer regulated as specified in the sprinkler specifications to minimise spray pattern wind drift.
How do I Lift the Riser of a
Pop-up Sprinkler?
To lift the riser of a rotor sprinkler, most require a Key inserted into the turret top of the sprinkler to lock into the mechanism and allow easy uprooting of the riser by hand. Any maintenance or switching of nozzles is often carried out in this way. Alternatively, ask a friend to switch the system on manually and catch the riser as it lifts during system operation.
